Fiber to the Home

From EverybodyWiki Bios & Wiki



Fiber optic service options.

The Fiber To The Home, also known as FTTH, included within the FTTx technologies, refers when the optical fiber reaches the boundary of the living space, such as a box on the outside wall of a home. Passive optical networks and point-to-point Ethernet are architectures that are capable of delivering triple-play services over FTTH networks directly from an operator's central office. Typically providing between 1 and 10 Gbit/s.

Many operators are reducing their promotion of ADSL services in favor of fiber optics, with the aim of offering very fast broadband services to users.

Architecture

FTTH technology proposes the use of optical fiber to the home of the user or fiber customer, also known as the "end user". The access network between the subscriber and the final distribution mode can be implemented with one or two optical fibers dedicated to each user (a point-to-point connection resulting in a star topology) or a passive optical network (PON), which uses a tree-like structure with one fiber on the network side and several fibers on the user side.

  • Passive optical splitter-based architectures are defined as systems without active electronics in the loop, with the main component being the beam splitter device. Depending on the direction of the light beam, it divides the incoming beam and distributes it to multiple fibers or combines it within a single fiber. The philosophy of this architecture is based on sharing the costs of the optical segment among the different terminals, thereby reducing the number of optical fibers. Thus, for example, using an optical splitter, a video signal can be transmitted from one source to multiple users.
  • The star topology provides one or two dedicated fibers to a single user. It provides the highest bandwidth, but requires cables with a greater number of optical fibers in the communications center and a greater number of laser emitters in the telecommunications equipment.

Regarding distributed architecture

Distributed network architecture is recommended. This means that passive elements will be distributed as close as possible to the end customer, minimizing fiber optic costs. However, the main objective is not to minimize fiber costs, but rather to design a network that is easily scalable in the future, leveraging the resources of the initial design. With the lowest possible investment, this will allow for increased coverage areas in the event of urban growth. It is recommended to distinguish three branches, with the following characteristics for fiber optic distribution:

  • Feeder or trunk. This is the route for each fiber optic pair from the Central Switch Point to the first passive element or splitter. It is essential and mandatory that the feeder route allow multiple fiber optics to allow multiple operators to use the GPON network.
  • Distribution. This is the route between the feeder and the final distribution point, from which individual optical fibers depart toward each ONT or customer. The closer the distribution fibers are to the intended area, the less fiber they reach the final subscriber. If possible, it is recommended to install an ODF (Optical Distribution Frame) or distribution boxes whose dimensions adapt to the civil infrastructure. For example: ODFs in the form of wall or floor boxes for access to buildings with a high customer density, or small distribution boxes that can be placed on poles in blocks with a low density of end customers.
  • Subscriber Access. This refers to the route from the customer's ONT location to the nearest pole junction, or connection point. In areas with low residential density, the final subscriber access route can be made via overhead cabling from the customer's home to the nearest pole that connects to the GPON distribution network. In areas with higher residential density, such as buildings, it is recommended to install a box or ODF, at the base of which the subscriber access fibers will originate.

Availability

North America

In the United States, the telecommunications company Verizon stands out, with investments exceeding 60 billion dollars until 2010, seeking to reach 14 million homes with FTTH; SBC, with an investment of 6 billion dollars in the next 5 years, to reach 18 million homes with FTTH; and BellSouth, with an investment of 3.5 billion dollars in the next 5 years to reach 8 million connected homes. President Barack Obama started the ConnectHome program..[1], Its objective is to bring high-speed Internet to 275,000 low-income homes, and even to a tribal nation, the Choctaw Nation. The program has the participation of several department stores, including Best Buy[2]. The project's main goal is to increase access to information for many children who can only connect to the Internet at their schools, thus creating an academic gap with respect to those children who have a connection at home.

  • In Mexico, fiber optic-based services began to be offered in the 2010s. The companies offering this service are:

  • In Uruguay, in 2011 the state-owned company Antel began laying fiber optics in Montevideo and by mid-2012 in more than 20 towns in the interior, the initial plan is for the entire country to have fiber in the home by 2014. On October 19, 2011 the first home was connected to Antel's fiber optic service. By the end of 2014, 40% of all homes connected to the Internet. In total, in Uruguay, more than 72% are connected to the Internet and more than 90% of homes with fiber past will be switched to fiber for free.[27] Until the end of 2014, it has offered connections from $ 28 for 20 Mbps up to 120 Mbps for $ 65.[28] ​The widespread change to fiber optics that Antel bet on, generated a strong impact on connection speeds, currently Uruguay is the country with the highest download and upload speed in Latin America very close to the US and Canada. At the end of 2014, Antel announced the laying of a submarine cable in association with Google, Angola Cables and Algar Telecom of Brazil that will connect Uruguay, passing through Santos and Fortaleza, directly with the USA.[29] ​considerably increasing speed, obtaining more independence from international connections and reducing connection costs by 195 million dollars.
  • In Bolivia, fiber optic coverage is very limited.
  • In Venezuela, the state-owned telecommunications company CANTV began FTTH implementation tests in July 2013 in Caracas, achieving speeds of up to 20 Mbit/s.[30] Finally, on August 22, 2019, investments were approved for the Fiber Optic Reaches the Home plan that will allow high-speed Internet access to offices and homes, initially covering the Capital District and the states of Miranda and Zulia and then, in November, it would reach 80% of the national territory.[31][32] However, due to the situation in the country, CANTV did not have the necessary resources for the necessary investment and began to issue contracts to third parties; as well as increasing the offer of bandwidth to these companies; a unique situation never seen before in Venezuela due to the hegemony that CANTV had over the country's networks since its nationalization on May 21, 2007.[33] From these new contracts, companies such as Airtek, Thundernet, Fibex, Vnet, +Planet and others that were already in the country such as Intercable, TvZamora and Netuno would increase their bandwidth and begin the migration to FTTH; with Airtek and Thundernet having the highest percentage of customers in the Zuliana and Centroccidental regions; Fibex in the central region and part of the plains; Vnet, Intercable and +Planet would be the first to offer fiber in the Andes, Llanos and Guayana regions; Netuno, Airtek, Intercable and Thundernet would be present in the Capital and Eastern regions; due to the emergence of the aforementioned companies, CANTV would have lost a significant number of subscribers; Unfortunately, the company has not provided figures since 2022.

Asia

  • South Korea is the country in the world with the highest broadband penetration, with 58% implementation in homes in 2011.[34] The launch of "lu-Korea vision" aims to position Korea at the forefront of the world, with its first commercial FTTH offers having already taken place in April 2005.
  • In Japan, where broadband penetration already reaches 40% of the population, there were already more than 3 million homes connected to FTTH by mid-2005 and forecasts point to 30 million customers by 2010, with leading companies such as NTT announcing €38 billion in investment to achieve this goal.

Europe

  • In France, Free has announced its FTTH project and has acquired Cité Fibre, which already offers fiber optics to the home at speeds of 100 Mbit/s and Triple Play services with an initial deployment in different districts of Paris through the company Nicominvest, while France Telecom intends to deploy its own fiber optic network with a potential market for 2008. However, in France, in 2009, the majority of very broadband network customers were in FTTH, through Numericable. Operators are waiting for legislation on fiber mutualization before doing more FTTH. In 2013, Free is a marginal player in this market developed by Orange, SFR Bouygues and Numericable.
  • In the Netherlands, residents of the town of Nuenen have built their own 1,000 Mbit/s symmetrical FTTH infrastructure, the first such alternative in Europe to traditional telecom operator models. KPN Telecom is preparing to expand its fiber optic network from the Netherlands and Germany, offering a potential market of over 25 million customers.
  • In the United Kingdom, NTL is conducting the necessary tests to be able to offer its customers 1,000 Mbit/s.
  • In Spain, several telecommunications companies offer fiber-to-the-home services, including:
    • GIT: In 2005, the Asturian government deployed the first fiber-to-the-home network in the mining valleys of the Principality of Asturias. This public capital investment aims to reconvert mining areas that have been depressed for years due to the decline of the sector. This is the first project of its kind in Spain, and a public company, the Gestor de Infraestructuras Públicas de Telecommunications del Principado de Asturias SA (GIT), has been created to manage this FTTH network and possible future public infrastructures. This project is known as the Asturcón network.
    • Cablex: On August 14, 2008, Cablex (Extremeña de Telecomunicaciones por Cable S.L.) acquired its first FTTH network customer after deploying 2,400 homes in Badajoz (Extremadura). At January 2015, Cablex offers 200 Mbit/s download and 100 Mbit/s upload connections to 20,000 homes.
    • Telefónica: Carried out the first field tests in Pozuelo de Alarcón and Campamento (Madrid),[35] reaching speeds of 500 Mbit/s. Since August 26, 2008, it commercially offers four Triple play packages over its FTTH network.[36] On November 13, 2008, the Telecommunications Market Commission authorized Telefónica to market this service, after verifying its correct operation. Today, Telefónica offers fiber at 700 Mbit/s in some areas of almost all Spanish capitals and in some other strategic geographical points, making deployment agreements with Jazztel and usage agreements with Yoigo.
    • Vodafone and Orange decided to join forces to make their own deployment of fiber optic internet that offers 1,000 Mbit/s download and 1,000 Mbit/s upload.
    • FibraCat: In September 2013, the company began offering connections of up to 1,000 Mbit/s download and 1,000 Mbit/s upload for residential customers in Catalonia, starting operations in Manresa. The town of Ermua has also joined the high-capacity Internet communications via optical fiber. Thus, since December 10, 2013, the neutral FTTH network began operating, reaching all individuals and businesses in the municipality and surrounding areas.
    • WI-NET: In Andalusia, in July 2014, the operator began migrating its own and franchised WiMAX networks in the provinces of Seville and Huelva to the new technology based on fiber to the home (FTTH), offering 100 Mbit/s connections as a basic plan, as well as HD Digital Television services over optical fiber.
    • Jazztel: offers a 200 Mbit/s symmetrical line. According to the February 2014 report by the CNMC, the total Broadband access park in Spain was 12,350,000 connections, of which approximately 1,453,000 would correspond to FTTH, with an interannual growth of 151.7%.[37]

Spain is carrying out a rollout in smaller towns, giving rise to access to Fiber Optic[38] for people who could not connect. With teleworking due to Covid, they are carrying out an acceleration to be able to promote the small towns of the famous Empty Spain that are fighting to stop the disappearance.

  • In Latvia, Lattelecom plans to deploy FTTH networks across 100% of the country, offering internet connection services of 500 Mbit/s, 200 Mbit/s, and 100 Mbit/s. These services are already available in the country's major cities.
  • In Andorra, STA (now Andorra Telecom) carried out the first pilot tests in early 2008, which served as a starting point for coverage to all Andorran homes by 2014. Since January 2009, it has been marketing FTTH with speeds of up to 100 Mbit/s with Triple play services .
  • In Romania, Digi (RCS-RDS) offers a 1,000 Mbit/s download and upload connection.

FTTH Networks Installation

For the installation and/or maintenance of FTTH networks, precision electronic instruments called FTTH analyzers are used to measure various parameters of the signals used in FTTH telecommunications technology. The parameters to be measured include optical power, MER, BER, symbol rate, etc.

FTTH is a term that even telephone operators themselves use confusingly. Sometimes, they use this acronym when they leave fiber optics in the housing community. This is a serious mistake: for a CTI (common telecommunications infrastructure) to be considered FTTH, the fiber must at least pass through the user's PTR (network termination point). From this point, the installation is up to the user, and they can decide what to do with the data transmission, whether to continue with fiber optics or coaxial cable. The PTR should not be confused with the socket. They are similar, but different: the PTR separates the installation from the home to the housing community. That's why we call optic fiber FTTH. If this occurs at the entrance manhole, it should not be considered FTTH.
